Research Tiers
So a friend and I are working on a mod, and he came up with the crazy idea to create "late game research" that would require more than the standard 8 research centers. I told him it wouldn't work because I was betting the number of tiers and the research stations associated with those tiers was hard coded. I.E. if I entered a tier value of '8' in (level 8 research is tier 7 in the files) I expect that game to crash. So my question is, is this hard coded or not? If not, how many theoretical tiers can I have? If it is, is there a way to change it, i.e. something in the game constants file or something similar.
